Query the parent (Jig) classloader prior to the project classloaders. Otherwise, Jig config resources (or other classes/resources from the base classloader) can't be found if no project classloaders are used (external project classloaders will automatically defer to the parent classloader).
Moving user.clj into source. Jig will only be invoked in dev mode (or at least, prod mode with a powerful continuous delivery reset capability!)
Moved docsite into a separate (nested) project and worked on documentary comments in sample.config.edn.
